The only reason they unbann you when they recieve Suicide threats.
Is because, people sometimes actually do suicide.
It starts off as a threat, then they don't get what they want. They go wdf, -dies-.
And then The company gets sued for not taking the suicide threat seriously.

They just don't wanna risk death, or getting sued as it'd ruin their reputation or drag them to bankrupcy.
It's not worth saying 'oh he's just bluffing'.
